Ultrasonic Spray Coating Process for Wafer Coating Ultrasonic Spray Coating Process for Wafer Coating - Cheersonic Behind the booming development of the modern electronic information industry, wafers, as the core carrier of integrated circuits or chips, play a vital role. Wafers are thin, circular sheets made of high-purity silicon. As a semiconductor material, silicon's conductivity can be precisely tuned by doping with various impurities, enabling diverse functions. The [...]

Polyimide Coating System The following is some information about polyimide coatings: Basic Concepts: - Definition: The "PI" in PI coating stands for polyimide, a high-performance synthetic polymer. PI coatings are primarily composed of polyimide, an aromatic heterocyclic polymer containing imide groups in its molecular structure. - Characteristics: Polyimide exhibits excellent thermal stability, mechanical strength, and chemical stability, which contribute to the excellent performance of PI coatings. Performance Characteristics: [...]

Ultrasonic Spraying Machines Apply Photoresist onto Glass Ultrasonic spraying machines utilize ultrasonic vibrations to create an atomization effect. They are suitable for small-batch production and qualitative testing in scientific research laboratories. When applying photoresist onto glass, ultrasonic sprayers can provide uniform and efficient thin-film coatings. Ultrasonic spraying technology demonstrates advantages for directly applying photoresist coatings onto MEMS wafers and other 3D microstructures, particularly on the sidewalls and tops [...]
